JEE Main 2027 Physics

A special orientation chapter for JEE Main 2027 Physics. It lays out the exam pattern and marking scheme, the chapter-wise weightage and priority, and the complete unit-wise NTA syllabus — every topic across Class 11, Class 12 and the experimental-skills section — followed by a short guide to how the rest of the course is organized. Use this chapter to see exactly what is examinable and where the marks are.
